I'd like a search engine to let you find players by typing their names or nicks. It should link to profiles. It would be useful for example in case you read a post in gb by an unknown player and you want to know his ranking, history , etc. . It would be nice too if in profiles there were player's positions in the rankings (world rank, country rank, etc) with direct links.

Yeah, this would definitely be a good idea. There are so many people on the world ranking that it takes a few minutes to find someone if you just know their name. And if you just know their nickname, it can take much longer...
